One of the most important areas of study of the state institution ”Scientific and Practical Centre of The State Forensic Expertise Committee of The Republic of Belarus” (hereinafter referred to as “the Centre”) is plant objects research using sporo-pollen analysis. Sporo-pollen analysis is used in solving of trouble-shooting problems connected with identifying the territory by the character of flora while determining the time of a crime. The Center for the first time in the Belarusian expert practice conducts research on pollen and spores of plants for the purpose of attributing to one batch of psychoactive substances impregnated with inactive matrix of vegetable origin. In this article, we propose a variant of optimizing palynological expert studies which consists in creating reference information retrieval system ”PalExp” (hereinafter referred to as “RIRS”) in which all information about pollen contains. The architecture and the main components of such a system, the questions of creating categories of accounting in the context of peculiarities of pallinological expert research and related problems of the formalization of information presentation, the basic requirements for the formation and functioning of the RIRS are presented. Advantages of this system as compared to the traditional sources of dendrochronological information are presented. The execution of forensic-palynological expertise with RIRS has a number of advantages, namely: shortening the investigation time, obtaining weighty evidences, as well as providing additional guarantees against unreasonable bringing of citizens to criminal and administrative responsibility.

Key words: identification of objects, vegetable objects, forensic investigations, information search system ”PALEXP”.
